Tweaks comments around the touched-up parts. Also tweaks spacing
Also adds some spacing in all cases of Variant::`reference()`. This is a special for consistency, because it ends up making the cases more readable.
Replace all TODO uses of `#warning` by proper TODO comments, and will open
matching bug reports to keep track of them.
We don't have a great track record fixing TODOs, but I'd wager we're even
worse for fixing these "TODO #warning" so we should prohibit this usage.
- Outright disable spammy warnings due to past or present GCC bugs:
* `-Wno-strict-overflow` for GCC 7.
* `-Wno-type-limits` for GCC before 11 (regressed in 9/10, might work in
earlier releases but at this stage we don't care).
* `-Wno-return-type` for GCC 12/13 (regression, still not fixed).
- Enable extra warnings conditionally when broken on earlier GCC:
* `-Wnoexcept` was removed due to an upstream regression in GCC 9, could
be re-enabled (but commented out for now as we actually have `-Wnoexcept`
warnings to fix.
* `-Wlogical-op` was broken on our variadic templates before GCC 11, now
seems fine.
- Add leading and trailing spaces within dictionaries, as the `{}`
characters are hard to distinguish from `[]` on some fonts.
This is especially helpful with empty arrays and dictionaries.
Also fix broken `ERR_PRINT_ED` macro and simplify comments.
For the record these macros aren't used yet, they're intended to be used
where needed to surface messages in the toaster when useful to end users,
but we haven't done that codebase review yet.
This makes the setting easier to find, as research has found there are
numerous use cases to limiting FPS. This also improves documentation
related to the Engine property and project setting.
The project setting also works in projects exported in release mode,
so its location in the `debug/` section was misleading.
Android was the last platform to still attempt to disable RTTI (for binary
size), but both the Android editor and now the ICU library used by templates
need RTTI.
There could still be the possibility to support this for non-ICU template
builds (i.e. without the TextServerAdvanced module), but since this isn't one
of the build configurations we test regularly it's pretty risky to keep this
option only for that specific use case. And our code is already littered with
`dynamic_cast`s which weren't guarded with `!defined(NO_SAFE_CAST)`.
This eases transition from beta 1 to beta 2 so that users don't get a warning
about a missing feature. The names were just changed.
The old feature names are removed from project.godot when opening such a
project.

New `target` presets
====================
The `tools` option is removed and `target` changes to use three new presets,
which match the builds users are familiar with. These targets control the
default optimization level and enable editor-specific and debugging code:
- `editor`: Replaces `tools=yes target=release_debug`.
* Defines: `TOOLS_ENABLED`, `DEBUG_ENABLED`, `-O2`/`/O2`
- `template_debug`: Replaces `tools=no target=release_debug`.
* Defines: `DEBUG_ENABLED`, `-O2`/`/O2`
- `template_release`: Replaces `tools=no target=release`.
* Defines: `-O3`/`/O2`
New `dev_build` option
======================
The previous `target=debug` is now replaced by a separate `dev_build=yes`
option, which can be used in combination with either of the three targets,
and changes the following:
- `dev_build`: Defines `DEV_ENABLED`, disables optimization (`-O0`/`/0d`),
enables generating debug symbols, does not define `NDEBUG` so `assert()`
works in thirdparty libraries, adds a `.dev` suffix to the binary name.
Note: Unlike previously, `dev_build` defaults to off so that users who
compile Godot from source get an optimized and small build by default.
Engine contributors should now set `dev_build=yes` in their build scripts or
IDE configuration manually.
Changed binary names
====================
The name of generated binaries and object files are changed too, to follow
this format:
`godot.<platform>.<target>[.dev][.double].<arch>[.<extra_suffix>][.<ext>]`
For example:
- `godot.linuxbsd.editor.dev.arm64`
- `godot.windows.template_release.double.x86_64.mono.exe`
Be sure to update your links/scripts/IDE config accordingly.
More flexible `optimize` and `debug_symbols` options
====================================================
The optimization level and whether to generate debug symbols can be further
specified with the `optimize` and `debug_symbols` options. So the default
values listed above for the various `target` and `dev_build` combinations
are indicative and can be replaced when compiling, e.g.:
`scons p=linuxbsd target=template_debug dev_build=yes optimize=debug`
will make a "debug" export template with dev-only code enabled, `-Og`
optimization level for GCC/Clang, and debug symbols. Perfect for debugging
complex crashes at runtime in an exported project.
A priori this doesn't appear to be an actual bug, but a known consequence of
using UBSAN. We silence this one to still have the possibility to get more
warnings raised by UBSAN, in case they are useful.
Works around and closes#66343.
- `_DEBUG` is MSVC specific so it didn't make much sense to define for
Android and iOS builds.
- iOS was the only platform to define `DEBUG`. We don't use it anywhere
outside thirdparty code, which we usually don't intend to debug, so it
seems better to be consistent with other platforms.
- Consistently define `NDEBUG` to disable assert behavior in both `release`
and `release_debug` targets. This used to be set for `release` for all
platforms, and `release_debug` for Android and iOS only.
- Due to the above, I removed the only use we made of `assert()` in Godot
code, which was only implemented for Unix anyway, should have been
`DEV_ENABLED`, and is in PoolAllocator which we don't actually use.
- The denoise and recast modules keep defining `NDEBUG` even for the `debug`
target as we don't want OIDN and Embree asserting all over the place.
